When are you unable to blend data from two or more sources?

EXPLANATION

If there are no variables shared between each data source then you will not be able to do a data blend, because there is no information that can be related from one source to the other. However, this does not mean that the column headers (variable names) need to be an exact match. You can edit the relationships manually to point Tableau to the variables that have matching underlying values.
